“It’s so surreal to be a family of four now with the birth of our son, Zander, today but we feel so incredibly blessed for this little man!” Hartsock tells Us. “So far he’s the perfect baby.. sleeping, no crying and super chill. Let’s see how long that lasts. ;)”

The couple, who wed in January 2015 after meeting on the season 9 of The Bachelorette in 2013, are already the parents of son Asher, 2.

“I think we’re both very excited to be able to see Asher and the new baby, like, be brothers and have that bond,” Siegfried told Us earlier this month. “I’m excited.”

“It’s a …… BOY!!!!!!!” Hartsock captioned an Instagram video of Asher eating a cupcake filled with blue frosting. “Asher’s face is priceless! And we are beyond excited to have another baby boy join our family! Can’t even believe we’re already half way there to meeting him. Our hearts are so full right now.”

The wedding dress designer told Us earlier this month that her pregnancy this time around was “just a little bit harder” while she had her hands full caring for a toddler, but the months went by “so fast.”
